Severe Notes 4/25/13 When ML AND UL flow reach an updraft and that midlevel and upper level flow tends to be subsaturated‚ so there are 3 options with this upward rotating flow can go left right or down. Can’t go up because air tends to be denser then the updraft air. So if that air goes down it gains downward momentum. Bc that air gains downward momentum which will evap cool it will continue to gain neg buoyancy. Once at the surface you have your RFD. Large precip surrounding the updraft which

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

"Too much and too little of anything is bad. The why are students being given too much of homework these days? The trend shows that the amount of homework being given to the children has been continuously and significantly enhancing over the time since last few years. Yes‚ making the students learn well is important but that shouldn’t be combined with the pressure and burden on them. But also‚ it is something you cannot avoid and hence you need to learn how to manage the same. You need to develop

Models of the Atom a) Plum Pudding Model The plum pudding model imagines the atom as a positively charged entity that contains randomly dispersed (negative) electrons within it. It is called the plum pudding model because the electrons in the positively charge cloud resemble raisins in a pudding. Thomson realized that all atoms must contain electrons‚ and since the atoms had a neutral charge‚ they must also include protons. This led him and other to think of the atom as a positively charged

Unit 004: Understand how to apply scientific principles within mechanical services engineering Glossary of terms Term Explanation Alloy A metal made up of a combination of two or more materials. Atmospheric pressure The weight of air creates a pressure on the Earth’s surface and the pressure exerted by the weight of air pressing down on the ground below will vary depending on the ground’s height above sea level.

Act I Scene 1 Homework – Graphing a Wave Name: A vibration is a wiggle in time; a wave is a wiggle in space and time. In this exercise‚ you will explore that connection by transferring the motion of the second hand of a clock (a vibration‚ even if a slow one)‚ to a wave. Print out the image of a clock and open the spreadsheet called Grapher. You will find both of them in the same item where you found these instructions. Use a metric ruler to measure the displacement of the tip of the

Abstract: Is it possible to create a science fiction-type force field? The article begins with a person asking the staff of The Straight Dope Science Advisory Board a question concerning the possibility of creating a fiction-type force field. The staff member asks the person to clarify the question by asking if it is a force field that protects a ship‚ a tractor beam or something to keep prisons in holding. She then explains the different kinds of forces considered by physicists and how some
